On my foci it had a louder tone= hence the stealth muffler. Now it sounds similar to stock w/ a touch of header ting. On my v/8 cars not so much.

Not worthless, bad word choice but incomplete.

Worthless? I can tell that it pulls harder; it sounds mean, and it'll probably give me better gas mileage... I wouldn't call that "worthless." But each to their own.

That's good to know about the header! I don't think I want it much louder than it is now.

The whole point in me modifying my focus was to make it a better daily driver. for me that meant adding a few more whp and improving the suspension so doing a intake, tune and eventually a catback might be all I need to meet those goals.

After hearing my exhaust for the first time today- I second that. I may change my mind about getting a header all together now. I'm going to wait until the burn-in stage is over to make up my mind. My exhaust is louder than I thought it would be. Still not over bearing, but after then burn-in, and header, it might be.

Still getting a tune no matter what!

Amen to that, i've never been afraid to do things that people said couldn't be done, or shouldn't be done due to this theory or that one..and sometimes I've had big wins, and other times, the experiment failed miserably...but I've said it before, the community needs to take risks and try some new things, not just
mass produced parts, of which there are suprisingly few for the MK3. Or perhaps not suprising given the huge gap in performance between the MK3 and ST.

It's a dct, I may dyno it after the tune. My butt dyno likes it lol

If i find that that large of an exhaust does in fact not result in a large low end loss (despite what ive encountered in my own experiences) then ill be the first to say im wrong..but i guess im old.school and i need proof and/or experience it myself rather then taking someones comments as gospel.

I don't expect my words to be taken as gospel; I'm simply relaying what was learned years ago. Even Tom has told you the same thing I have, and anyone that has been on this forum for almost any length of time knows that Tom and I disagree more often than not. But either way, this was not a forced-induction car-

I'm all about testing and would enjoy seeing more done on this platform, even if it's the same stuff that was done years ago. Not all of that data still remains, and a community can never have 'too much' to analyze. Unfortunately though, we usually have more armchair quarterbacks that usually don't follow through with testing despite their firm opinions/beliefs than we have of people that actually do legitimate testing.

I can relay my experience and what I've seen, but if that somehow translates to me not modifying enough cars...Idk what to tell you. My Mk3 was one of the most modified and recognized in the community when I had it, and I've since bought and taken both of my ST's to stage 3 and then began doing my own tuning. And no offense, but that's just the last three years.

I'm not perfect, but I don't have a very strong record of being wrong.

Ive had 4-1 and 4-2-1 headers on about 6 different cars and adding the header didnt make the exhaust appreciably louder, in fact it made the.exhaust note.deeper
